(contactmusic.com) - Singer Justin Timberlake has hired a top barbecue chef to help him combat the mixed reviews his New York restaurant has received in its first nine months. Cook Ray 'Dr. BBQ' Lampe has been brought in to revamp the menu at Timberlake's Southern Hospitality, after some restaurant critics were left less than impressed. One writer at website NYMag.com even described the food there as "awful". And Lampe is determined to start with the diner's ribs and work his way up: "We want them to be competition-style (ribs), where when you take a bite the meat comes off easy, but doesn't just slide off the bone. I don't think the guys that were in charge before really got that." Timberlake and his best friends Eytan Sugarman and Trace Ayala launched Southern Hospitality in July 2007.
